[(3)H]noradrenaline ([(3)H]NA) released from sympathetic nerves in the isolated main pulmonary artery of the rabbit was measured in response to field stimulation (2Hz, 1ms, 60V for 3min) in the presence of uptake blockers (cocaine, 3 x10(-5)M and corticosterone, 5 x10(-5)M). The [(3)H]NA-release was fully blocked by the combined application of the selective(More)
Low frequency (2 Hz) of electrical depolarisation induced [3H]noradrenaline ([3H]NA) release has been measured from the isolated main pulmonary artery of the rabbit in the presence of uptake blockers (cocaine, 3x10(-5)M and corticosterone, 5x10(-5)M), with parallel measurements of post-junctional contractile responses. The K+ATP-channel opener pinacidil(More)
1. The spontaneous [3H]-release has been measured from the isolated main pulmonary artery of the rabbit preloaded with [3H]noradrenaline in the presence of uptake blockers (cocaine, 3 x 10(-5) M; corticosterone, 5 x 10(-5) M). 2. The Ca-ionophore A-23187 (3 x 10(-7)-3 x 10(-5) M) increased the outflow of [3H] by a concentration dependent manner. 3.(More)

The release of [(3)H]noradrenaline has been measured from the isolated main pulmonary artery of the rabbit in the presence of uptake blockers (cocaine, 3 x 10(?5) M; corticosterone, 5 x 10(?5) M). K(+)-removal from Krebs solution increased the release of [(3)H]NA even in the absence of external calcium. K(+)-readmission to the external medium terminated the(More)
